[Nix-dev] warning: name collision in input Nix expressions

[Bjørn Forsman]

Hi,

"nix-env -u --always" has stopped working on my laptop. Any ideas?

$ nix-env -u --always
warning: name collision in input Nix expressions, skipping
`/home/bfo/.nix-defexpr/channels_root/nixos'

I don't remember doing anything special to it. It should be pretty
identical to my dekstop system where this command is working just
fine.

Best regards,
Bjørn Forsman
